【项目经验】：elementui表格中表头的多选框换成文字

一.项目需求

        表格可以多选，表头都是汉字。。。。类似于这种

        

二.实现功能

• 用到的方法

• 实现代码（可复制直接跑）

HTML部分

<template>
    <div class="Box">
        <div>
            <el-table ref="multipleTable" :data="tableData" tooltip-effect="dark" style="width: 500px"
                @selection-change="handleSelectionChange" :header-cell-class-name="cellClass">
                <el-table-column type="selection" width="55">
                </el-table-column>
                <el-table-column label="日期" width="120">
                    <template slot-scope="scope">{{ scope.row.date }}</template>
                </el-table-column>
                <el-table-column prop="name" label="姓名" width="120">
                </el-table-column>
                <el-table-column prop="address" label="地址" show-overflow-tooltip>
                </el-table-column>
            </el-table>
        </div>
    </div>
</template>

js部分

<script>
export default {
    name: "list",
    data () {
        return {
            tableData: [{
                date: '2023-09-03',
                name: 'bug天选之子',
                address: 'https://blog.csdn.net/weixin_70245286?spm=1000.2115.3001.5343'
            }, {
                date: '2023-09-03',
                name: 'bug天选之子',
                address: 'https://blog.csdn.net/weixin_70245286?spm=1000.2115.3001.5343'
            }, {
                date: '2023-09-03',
                name: 'bug天选之子',
                address: 'https://blog.csdn.net/weixin_70245286?spm=1000.2115.3001.5343'
            }, {
                date: '2023-09-03',
                name: 'bug天选之子',
                address: 'https://blog.csdn.net/weixin_70245286?spm=1000.2115.3001.5343'
            },],
            multipleSelection: [],
        }
    },


    methods: {
        // 选中的项
        handleSelectionChange (val) {
            this.multipleSelection = val;
            console.log("选中的项:", this.multipleSelection);
        },
        // 修改多选框表头
        cellClass (row) {
            // 判断第几列
            if (row.columnIndex === 0) {
                return "disableSelection";
            }
        }

    },
    mounted () {

    }
}
</script>

css部分

<style scoped>
.Box {
    display: flex;
    justify-content: center;
    align-items: center;
}

::v-deep.el-table .disableSelection .cell .el-checkbox__inner {
    display: none;
    position: relative;
}

::v-deep.el-table .disableSelection .cell::before {
    content: "选项";
    position: absolute;
    right: 15px;
}

::v-deep.el-table {
    border: 1px solid blue;
}
</style>

实现后的效果图

三.总结

关键代码

// 在表格上绑定header-cell-class-name属性
<el-table ref="multipleTable" :data="tableData" tooltip-effect="dark" style="width: 500px"
                @selection-change="handleSelectionChange" :header-cell-class-name="cellClass">
// 在methods中判断确定是第一列然后给对应的class名
cellClass (row) {
            // 判断第几列
            if (row.columnIndex === 0) {
                return "disableSelection";
            }
        }
// css做对应修改

// 隐藏多选框表头
::v-deep.el-table .disableSelection .cell .el-checkbox__inner {
    display: none;
    position: relative;
}
// 替换后的表头内容（根据需求自行设置）
::v-deep.el-table .disableSelection .cell::before {
    content: "选项";
    position: absolute;
    right: 15px;
}
